Century ride (100 mi) training plan — beginner

A 10-week century ride (100 mi) training plan at beginner level — designed around 5 hours per week across 4 days. Polarised intensity distribution: most volume at easy aerobic effort, two quality sessions, one long ride.

This is the representative template. The real SportPlan plan rebuilds every day from your Garmin and Strava data — HRV trend, Training Status, recovery, race calendar. The structure stays the same; the adaptation day-to-day is what changes.

Mon

Rest day

Full rest. No training. Sleep priority, normal eating, light walking only if you want.

Tue

60 min

Sweet-spot intervals

Target zones

Sweet spot (88–94% FTP)

Why today

Highest sustainable training intensity for cycling — efficient FTP building per unit of fatigue cost.

Session details

Warm-up 10 min. 3×12 min at sweet spot (88–94% FTP) with 4 min recovery between. 10 min cool-down.

Wed

Rest day

Full rest. No training. Sleep priority, normal eating, light walking only if you want.

Thu

68 min

Endurance ride

Target zones

Z2 endurance (55–75% FTP)

Why today

Aerobic base. 70–80% of weekly volume sits here. Mitochondria, capillary density, fat oxidation.

Session details

Steady aerobic ride at Z2. Cadence 85–95 rpm. Stay conversational throughout.

Fri

Rest day

Full rest. No training. Sleep priority, normal eating, light walking only if you want.

Sat

105 min

Long ride

Target zones

Z2 endurance (55–75% FTP)

Why today

Glycogen depletion + slow-twitch fibre recruitment. The single most important session for endurance events.

Session details

Long endurance ride at conversational pace. Fuel 60g carbs/hr + bottle of mix per hour.

Sun

How this plan is structured

Polarised intensity distribution: roughly 75–80% of weekly volume at easy aerobic effort, 15–20% at quality (threshold, intervals, tempo), and 0–5% at race-pace. This split is the most-supported intensity distribution in the published endurance-training literature.

Quality sessions placed Tuesday and Thursday with full recovery between. Long session on Saturday (running / cycling) or Sunday brick (triathlon). Rest day Monday or Friday depending on your days-per-week.

Each session in the engine comes with a one-line 'why today' explanation. In the real adaptive plan, that rationale is anchored to your HRV, Training Status, and recent load — not the static template you see in this sample.

Methodology

Methodology designed by Ramon Curto, MSc Exercise Physiology

Ramon Curto designed SportPlan's endurance-training methodology from exercise-physiology principles. SportPlan applies it autonomously to the information you enter and the data you choose to connect; it is not ongoing one-to-one coaching or medical care.
